v0.4.0: Merge pull request #19 from vsco/watcher

• Watch for changes instead of polling for changes. Updates essentially happen in real time.

v0.3.1

• Minor change in which order the watch runs.

v0.3

• Set consul key with json value.
• Make jsonconsul a library to be used by other apps.

v0.2

• Major refactor of the code.
• Handle JSON Consul values much more gracefully instead of always thinking it's a string.
• Remove prefix keys if they are not needed.
